- Is it an ESP32-S2/S3/P4 native USB Host or it needs an external MAX3421 IC ?
- FS or HS ?
@lyusupov it's for native USB host. Speed depends on the chip. FS for S2 and S3 and HS for P4
That's great!
Waiting patiently for your merge of this PR into upcoming Release.
Will be happy to try it out on P4 in HS mode with USB RTL-SDR receiver (and libusb driver).

This pull request enhances TinyUSB integration in the Arduino ESP32 project by expanding support for USB host functionality alongside device mode. The changes update build configuration, add host-related source files, and introduce new host-specific settings and code patches to enable and configure the host stack.
Build system and source file updates:
usbh.c,hub.c, host class drivers) to thesrcslist incomponents/arduino_tinyusb/CMakeLists.txt, enabling compilation of USB host features. Also updated device and common file inclusion for TinyUSB. [1] [2]Configuration and settings:
tusb_config.h, such asCFG_TUH_ENABLED,CFG_TUSB_RHPORT1_MODE, and buffer/device limits for host mode. Also added board-level defines for host port and speed.CFG_TUD_ENABLEDwhenCONFIG_TINYUSB_ENABLEDis set, and added board-level macros for device port and speed. Improved memory alignment handling for ESP32P4 targets. [1] [2] [3]Code patching for host support:
dwc2_esp32_h.diff) to the TinyUSB source, updating interrupt handler logic to call both device and host interrupt handlers as appropriate. [1] [2]
